Two mental health professionals previously found Moreno was insane at the time of the incident, something neither the prosecution or defense contested during trial.

The dispute between attorneys comes when considering whether Moreno did anything ahead of the attack that exacerbated his psychosis. He'd previously been diagnosed with schizophrenia, according to court testimony.

During his closing argument, First Assistant District Attorney Matt Manning argued Moreno knew his psychosis is enhanced when he smoked marijuana. He said Moreno had smoked in the weeks before the February incident.

"If you know introducing cannabis into your system may give you the prolonged effects of worsening your psychosis, then your criminally responsible," Manning told the Nueces County Jury.

Moreno's defense attorney David Klein argued it had been proven Moreno was insane at the time of the offense and said there's no evidence Moreno was intoxicated or "suffering from the effects of intoxication" on Feb. 7.

"You must return a verdict of not guilty of reason by insanity because that's what the evidence in this case requires you to do," Klein said in his closing. He declined comment after the trial ended.

Manning said he thinks the jurors were given a tough case to deliberate.

"We readily concede that he had a mental illness and we sympathize with the affliction for both him and his family and for the people who were hurt by the way it sympathized this time," Manning said.

"However, our law has a number of different carve outs and exceptions and kind of ad hoc approaches to situations, and this is one that we felt in our estimation kind of fell on the line, so we wanted to see what the community's response to it would be," he continued.
